You’re going to adore this recipe for a bunch of reasons. First, it’s a fantastic way to avoid food waste while getting a seriously delicious meal on the table. We’re talking about a hot, toasty sandwich packed with tender steak, melty cheese, and savory onions and peppers. So, so comforting.

It’s the perfect solution for a busy weeknight when you want something satisfying without a lot of fuss.

Ingredients You’ll Need

• 2 tablespoons olive oil: To get those onions and peppers sizzling.
• 1 large green bell pepper, thinly sliced: For that classic Philly crunch and sweetness.
• 1 medium yellow onion, thinly sliced: Adds a savory, caramelized flavor.
• 2 cloves garlic, minced: Because a little garlic makes everything better.
• 12 ounces cooked steak, thinly sliced: The star of the show! Use any leftover steak you have.
• 4 hoagie rolls or sub rolls: The sturdy vessel for all that goodness.
• 8 slices provolone cheese: For that iconic, stretchy melt.
• 2 tablespoons butter, softened: To create the most golden, buttery crust on the bread.
• Salt and black pepper to taste: To wake up all the flavors.

Let’s Get Cooking Step by Step

1. Heat the olive oil in a large skillet over medium heat. Add the sliced peppers and onions and cook, stirring occasionally, until they’ve softened and started to get some golden-brown spots, about 8-10 minutes. Toss in the minced garlic and cook for one more minute until fragrant.
2. Add your thinly sliced leftover steak to the skillet. Give everything a good stir and cook just until the steak is heated through, which should only take 2-3 minutes. Season with a good pinch of salt and pepper.
3. While the steak mixture is heating, split your hoagie rolls open but don’t separate the halves completely. Spread the softened butter on the inside and outside of each roll.
4. Divide the warm steak and veggie mixture evenly between the rolls. Top each pile with two slices of provolone cheese.
5. Carefully close the sandwiches. Wipe out your skillet and place it back over medium-low heat. Place the sandwiches in the skillet and press down gently with a spatula. Grill for about 3-4 minutes per side, until the bread is beautifully golden and toasty and the cheese is completely melted. If you have a panini press, feel free to use that instead!
6. Slice each sandwich in half and serve immediately. So good.

Leftover Steak Dinner Ideas

If you find yourself with more leftover steak, don’t let it go to waste! There are so many easy and delicious routes you can take. Toss thinly sliced steak into a salad for a protein-packed lunch. Whip up a quick steak fried rice by sautéing it with day-old rice, veggies, and a splash of soy sauce. One of my favorite leftover steak pasta recipes involves slicing it up and stirring it into a creamy Alfredo or marinara sauce right before serving. For a super simple meal, just chop it up for tacos or a hearty omelet filling. The possibilities are truly endless!

Variations & Substitutions

This recipe is wonderfully flexible. Not a fan of provolone? Swiss or mozzarella cheese will work perfectly. If you want a little kick, add a sliced jalapeño to the pepper and onion mix while they sauté. For a lighter option, you can skip the butter on the rolls and just give them a quick toast. And if you don’t have hoagie rolls, any sturdy bread you have on hand will do—even a large tortilla for a steak wrap! Honestly, if you’re looking for more leftover beef recipes, this basic formula is your best friend.

Serving Ideas & Pairings

These sandwiches are a full meal all on their own, but if you want to round things out, a simple side is the way to go. A crisp green salad or a handful of potato chips are classic pairing choices. For a heartier dinner, a bowl of tomato soup or a side of sweet potato fries would be absolutely delicious. And a cold glass of iced tea or lemonade is the perfect drink to wash it all down.

Storage & Reheating

These sandwiches are definitely best enjoyed right away, but if you have leftovers, you can store the filling separately from the rolls in airtight containers in the fridge for up to 2 days. To reheat, warm the steak and veggie mixture in a skillet over medium heat until hot. Assemble your sandwich fresh to keep the bread from getting soggy. I don’t recommend freezing the assembled sandwiches, as the texture of the bread and peppers won’t hold up well.

Frequently Asked Questions

• What’s the best way to slice the leftover steak for these sandwiches? You’ll want to slice it as thinly as you can against the grain. This ensures every bite is tender and easy to chew, especially since we’re reheating it.
• Can I use a different type of meat? Absolutely! This method works great for any leftover beef recipes. Leftover roast beef or even shredded chuck roast would be fantastic here too.
• My steak is a bit dry. How can I prevent that in the sandwich? This is a common worry with leftovers. The trick is to not overheat it! Just a quick 2-3 minutes in the pan with the peppers and onions is plenty to warm it through without drying it out further.
